NSX for vSphere Design

<

Each NSX instance is tied to a vCenter Server instance. The design decision to deploy two vCenter Server instances per region(SDDC-VI-VC-001) requires deployment of two separate NSX instances per region.

SDDC-VI-SDN-001

Use two separate NSX instances per region. One instance is tied to the Management vCenter Server, and the other instance is tied to the Compute vCenter Server.

Software-defined Networking (SDN) capabilities offered by NSX, such as load balancing and firewalls, are crucial for the compute/edge layer to support the cloud management platform operations, and also for the management applications in the management stack that need these capabilities.

You must install and perform initial configuration of multiple NSX instances separately.

SDDC-VI-SDN-002

Pair NSX Manager instances in a primary-secondary relationship across regions for both management and compute workloads.

NSX can extend the logical boundaries of the networking and security services across regions. As a result, workloads can be live-migrated and failed over between regions without reconfiguring the network and security constructs.

You must consider that you can pair up to eight NSX Manager instances.
